BOD, COD, and TOC - Wastewater Treatment

Most industrial wastewater treatment plants use chemical oxygen demand (COD) rather than the BOD5 test. Due to the length of time required to complete the BOD5 test (five days), BOD results provide historical data only and do not facilitate rapid water quality assessment for optimal process control.

The takeaway from this is that the COD/BOD ratio is not only variable, it is also plant and waste stream specific. Often, an industrial plant won't have both BOD and COD data so the true ratio cannot easily (immediately) be determined.
